I'm sorry, but I don't know what you're talking about.
It sounds like you may be working with some game engine, and possibly that game engine uses AngelScript as the scripting engine. If that is the case you need to ask the game engine's author how to do the task you desire to do, as it doesn't depend on the language but rather on what interface the game engine is exposing to the scripts.

That would be a function provided by the Ethanon engine. You'll need to check the manual for Ethanon, or ask on the Ethanon forums for help on using it.
